IMPROVEMENT-IN FARM-GATES.

Specification forming part of Letters Patent No. 180,297, dated July 25,1876; application led January 4, 1876.

' scription and accompanying drawings are sufficient to enable anyperson skilled in the art or science to which it most nearly appertains.

to make and use my said invention 'Without further invention orexperiment.

The object of my invention is to provide a cheaply-constructedfarm-gate, which can he opened and closed by persons on horseback and invehicles without the necessity of their dismounting. y In order todescribe my improved gate reference is had to the accompanying drawing,forming a part of this specificatiomin which- Figure l is a perspectiveview of my gate.

A B are the posts on each side of the gateway, between which the gate Cis to pass in opening and closing. In the ground, between these twoposts, I sink a timber, D, so that its upper face will be level with thesurface ofthe ground, and the timber extends past the post B, and farenough beyond it, to provide a bearing or track for the gate tore'st'upon when it is open. The upper surface of the timber D has agroove, e, which extends its entire length, so as to provide a track andguide for the gate to lnove in. Rollers f j' are secured to the loweredge of the gate, and these rollers bear upon the bottom ofthe groove e,so as to relieve the friction and permit the gate to move easily whenbeing' opened and closed. Ihe upper edge of the gate is steadied andheld in place by a hook-shaped guide, H, which is secured to the post B,so that the edge of the gate will move in the opening of the hook.

At the desired distance upon each side of the gate C I plant a post, I,so that both of these posts will be in line, or nearly so, with the postB of the gate. To each post, I, I secure a casting, K, which has an arm,L, extending out toward the middle of the roadway. A shaft, M, extendstransversely across the end of the closed gate, its opposite ends beingsupported in the castings K on the posts I.

`is secured in one groove of the pulley O.

Another cord, q, has one end secured to the forward upper corner of thegate, while its opposite end is passed in an opposite direction aroundthe other groove of the pulley, so that, when the shaft is rotated, onecord will wind upon the pulley, while the other unwinds, according tothe direction of rotation, thus opening and closing the gate. [n orderto rotate the shaft M, I secure ashaft, Q, in each casting K, at rightangles to each end of the shaft M, so that one end will bear in thecasting while the opposite end is supported at the. arm L over themiddle of the roadway. The inner end of each shaft Q has a bevel-wheel,R, which engages with a bevel-wheel, S, on the end of the shaft M, and acrank, T, on the outer end ofthe shaft, serves to rotate it.

A person approaching the gate has only to grasp the crank T of the shafton whichever side of the gate he happens to be, and turn it from him.This causes the shaft M to rotate and wind upon the forward cord, andlet off the rear cord, thus opening the gate. When he has passedthrough, a similar winding of the opposite crank T rotates the shaft Min an opposite direction and closes the gate.

I thus provide a cheap, easily-operated, and substantial farm-gate,which can be opened without (it-:mounting from a horse or vehicle.

Having thus described my invention, what I claim,- and desire to secureby Letters Patent, is- Y i l In combination with the sliding gate C thetransverse shaft M, with its double pulley 0,

and the separate cords p q, operated by the transverse crank-shafts Qand bevel-gears R S, substantially as and for the purpose described.
